![]() ![]() The water pump is the engine accessory that pumps the coolant through the Tacoma’s engine. Here’s more on Toyota Tacoma thermostat diagnosis. Heat is needed for efficient combustion, and for the heater to work properly. If the thermostat wasn’t there, the engine would always run cool. This regulates the amount of coolant flowing through the engine. While a thermostat is perfectly capable of functioning for the whole life of the vehicle, it’s still a common reason that you can be running hot.Īfter the engine temperature reaches a certain level, the thermostat automatically opens up. Your Tacoma’s thermostat is the gatekeeper that keeps the coolant from entering and exiting the engine. ![]() Some people have success using a cure in a bottle cleaner. In this situation, you’ll need to take your radiator to a shop to have it repaired. ![]() As time goes by, the radiator will only get worse until it can no longer cool the engine. ![]() This is a likely scenario when your engine is running hot but not overheating. It can become so grimmy with deposits that it can no longer cool the engine all of the way. Simply put, the radiator is a series of finned tubes that cool the coolant so that it can return to the engine and pull more heat from it. The coolant exits the engine and enters the radiator. Your Tacoma’s water pump pushes coolant through the engine. It’s much more likely to be the fan though. It can also be the thermostat that tells the fan when to come on or off that could be at fault. If it’s not, it’s almost certain that you need a new fan. With the vehicle in park, go ahead and pop the hood. When your engine is running warm, that fan should be on. It’s easy to tell if the radiator fan is bad or not. If the engine begins to cool off when you get onto the highway and into “clean” air, it very well could be the fan. You will notice that a fan is not working properly when the vehicle isn’t moving very fast. When you are out on the highway, the wind passing over the radiator is more than enough to keep it cool. The fan pushes air over the radiator to keep it running cool. A bad fan can cause your engine to run hot. This should be done with the engine cool.ĭepending on the model year and the engine, your Tacoma could have a clutch fan or an electric fan. It’s best to fill the overflow, let the engine cycle it through for a few minutes and start over again. If it’s starving for coolant, the dramatic temperature change can cause engine damage. It’s important that you don’t pour a bunch of coolant in your Tacoma while the engine is hot. You’re going to need the proper Toyota approved coolant and you’re going to have to fill it back up. If your engine is low on coolant, the overflow container should be empty all of the way, not just a little bit. It’ll have a line that says where the coolant should be if it the engine is hot or cold. There’s always coolant in there and it fills up a bit when the engine warms up. Modern vehicles use an overflow container. You almost never have to take off the radiator cap to check the coolant level. It’s highly likely that the coolant level is low, and it’s the easiest thing to check, so start there. The very first place that you would want to check if your Tacoma is running hot is going to be the engine coolant. Here are some of the most common reasons that your Tacoma would run hot: Anything else would be a symptom of overheating.
